1-5
Storytelling
Does your visualisation tell a clear, compelling story? We look for logical flow, context, and narrative progression that guides the viewer through your insights.
1-5
Design
Is your dashboard clean, readable, and visually appealing? We evaluate layout, typography, colour choices, and visual hierarchy.
1-5
Technical
Does your work demonstrate strong technical skills? We assess DAX usage, data modelling, chart type selection, and interactivity implementation.
1-5
Insights
Do you provide meaningful analysis? We look for non-obvious discoveries, actionable recommendations, and demonstrated business impact.

Pharmacy chains operating across multiple countries face ongoing commercial and operational challenges, and this dataset highlights several critical areas:
Operational & Analytical Challenges
Fragmented visibility across countries and regions makes it difficult to understand true business performance.
Variations in sales and profitability between pharmacies obscure which locations are truly driving value.
Seasonal demand fluctuations complicate inventory planning, staffing, and promotional timing.
High-volume products with low margins reduce overall profitability and distort performance reporting.
Limited insight into the effectiveness of promotions makes it hard to justify discounting strategies.
Differences between urban, suburban, and rural pharmacy performance are often poorly understood.
Inconsistent product and brand performance across regions complicates assortment and pricing decisions.
Lack of clear drill-down from country to pharmacy level limits accountability and local optimisation.
Geographic patterns in sales and margin are not always visible, leading to missed regional opportunities.
Difficulty linking regional performance to overall results weakens strategic decision-making.
Your report should address these gaps by uncovering trends, drivers, and outliers that help pharmacy leaders improve profitability, optimise operations, and make more informed commercial decisions.

Business users use reports to make data-driven decisions. That’s why reports are called effective if they enable users to drill down and filter data quickly and intuitively to find answers to any question they might have and analyze data in all possible directions and dimensions.
We will evaluate:
1) How easy is it to understand the data? (Max 10 points)
Is too much text used for explanation?
Are the indicative colors in charts instinctually understandable?
Does it tell a story?
2) How easy-to-use is the report? (Max 14 points)
Cross-chart filtering implementation across the report. Can other visuals provide relevant data as the user explores the report?
Response time
Drill Down: Multi-layer data exploration. Can the user drill down and gain additional insights within the report?
Use of tutorial overlays and other elements to assist new users. Can a new user start using this report straight away with just the guidance provided within the report itself?
3) How good is the report design and is it suitable for its purpose? (Max 10 points)
Visual design: Is the overall look consistent, no empty spaces, no overcrowding?
Interface design: Are there unnecessary visualizations/buttons/complexity in use?
UX design: Is the produced report usable?
Report design: Is the main challenge answered?
Technical: Are all the fonts used the same, are the sizes readable?
You are encouraged to use various techniques at your disposal, such as tooltips, drill-throughs, drill-downs, cross-chart filtering, and page navigation features, to enhance your analysis.
